ratus so arranged and 4elcctricziilly so inter# connected that a single electric generator may be employed for the purpose ot supplying electric current for the ignition system of an internal combustion engine, and may be contemporaneously employed to supply current i'ior lighting or other purposes.

My invention consists iii the use ci' an electric generator, in combination with an iii-- luctive means, a working circuit, and other electrical apparatus, substantially as hereinafter described, all being combined and elecinatter set forth.

The drawing presents diagianimatically one of the preferred embodiments ot' my invention.

In said drawing, 1 is an electric generator, preferably ot the direct current type, and provided with the usual conimutating brushes 2 and 3. f

At Il is indicated the primary winding ot an inductive means, preferably an induction coil; the secondary winding, fi, of the same being electrically connected to the spark points (i, v-.fliicli muy be located in any approved manner in the cylii'idcr ot' an internal combustion engine, not shown iii the drawings. y

A t 7 are indicated one or more electric lam s renrcsentinoV a workino` circuit. if

7 i. K7 D storage battery, which maybe ot any approved iiorm, is indicated by the numeral 8.

At 9 is represented. an electro-magnet which is adapted, when inagnetized, to cause a movement of av movable armature 10 carried upon a resilient strip 1l, which is of an electrically conductive material, and secured prceraljily at either end, as shown, upon supports 1Q land 15. Said stip 11 is have invented cerm` generator 1 will `the contact screw normally in contact with the tip of a contact screw 14C adjustably mounted in a support 15.

At 1o is represented the movable member of a contact making device, as for example.

the rotating arm of a timer; said arm being adapted to contact, as it revolves, with the timer segment 17.

At 18 is a condenser otany approved typel.

The electrical apparatus hereinabove men- *l* tioned are electrically connected by suitable conductors inthe following manner. The` coniinutating brush, 2, is cozinectedat support 13, with the resilient strip 11; the circuit extending through the contact sci ewv support 15, and the primary winding 4c of the inductive means. Leaving thek resilient strip 11 at the support 12, the .circuit dividesv into three branches, one branchleading through the working circuit containing `the lamps 7, and a second branch 1 leadingl through the storage battery 8,' to thebrush A third branch traverses the winding of said electromagnet 9T and is in electric connection with brush -at such times as the timer arm 1G and timer segment are in electrical engagement. The condenser 18 is connected in usual manner in shunt around the separable contactsl embodied in the re` silient strip 11 and the contact screw 14.

My invention operates in the following manner. The timer varm 16 is assumed to be rotatably driven'so as' to come into engagement with the timer segment 17 at such instant it is desired to produce a-spark' at the spark pointsy 6. Except at the inoI ments 'when hereinafter described, the magnet 9 is in a magnetized condition, the resiliency ot strip 11 is arranged to holdthe same in contact with the tip lof the Contacty screw 1li, which is so adjusted in its supportl .l5 as to bein electric engagement with the4 saine. Assuining'now that the generator 1- -is rotatably driven so as to generate electric energy, and furthermore for the moment assuming that the timer arm 1G isout ofen- `ga`genient withthe timer segment 17. it will be apparent that-:the current generated by pass by way of brush-2 into l 14 Vand thence into -the i'e'-, silient strip 11 whence it lwill return to brush il in part `through the working circuit 7 and iu part will operate to `charge the` storage battery allel therewith; the 'resistance comprise 8 which is connected in' are.,

bodied in the contact screw la and resilient x strip il being' relatively so low with respect to that comprised in the primary ll and the Contact screw le.

winding ol the induction coil, tbatrsaid Winding is essentially .short circuited and Will reinain in an unenergized condition and electrically inert. llhen however, the rotating arm 16 of the timer engages with the timer segment l?, 'the Winding of the electrocnagnet 9 will be connected'in parallel with the Working circuit 7 and With the storage battery 8, into the circuit included between the brushes 2 and 3, and a part of the current generated bythe generator will t'averse the .magnet Winding' and ywill inagnetize the saine.

The magnetization of the electro-magnet 9 'will operate to actuate the circuit breaker, the; attraction .ofthe magnet upon the armature l0 causing the separation of the separa; ble contacts carried upon the resilient strip ln consequence of the separation of the said separable contacts the current produced by the lf,:,'feiiei'ator l will `be suddenlycoinpelled to traverse the jgiriniary windings: oi the inductive means on its Way tothe. lighting and storage circuits. ln consequence, the sudden energica- Ation of the inductive nieans so produced, will operate in Well'lrnoufn inannerto induce a current in the secondary Winding of the saine which willicause a 'discharge at the spark vpoints 6. When the continued rota-` tion of the timer arm l@ has carried the saine out of engagement Twith the timer segment l?, the magnet 9 will lose its power oit attracting armature Jl and the resiliency ol3 strip ll. Willrestorethe same into its initial v strumentalities, `in 1 the manner A cated; said coil meanwhile discharging itself' position in contact 'arithcontact screw let ln ccnsequencethe primary Winding' l will be again short. circuited and current will cease to traverse the saineywhereupon said coil Will again become inert and will remain so until the timer again becomes operative to again actuate the ldischarge producing in just indibetween its successive energizatlons into the condenser 18 in usual manner..

By adopting the method hereinabove described whereby the linductive means is thrown into the circuit so as to be connected.

in series with the generator and the Working circuit momentarily lwhen it is desired. to

venergize the saine it is possible to utilize the energy developed by the generator Il for the vdouble purpose as fliereinabove described.

with comparatively slight disturbance to the operation of vthe Working circuit or the merging circuit. i

lily invention hereinabove c cscribed may be readily adapted for use inconnection with n :absence rnulti-cylindercd engines either by employ-v ing a low 'tension distributor adapted to place a selected induction unit in operative relation to the system, or by using a high tensiondistributer :t'or the purpose or' placing the inductive means in operative relation with sparlt points llocated in a selected motor cylinder. The inodications neces sary to ellect either o t the above constructions suggested .may be easily effected by any competent Worlnnan experienced in ignition work, so .l will not describe such modifications in detail. At the saine time .inodilications, of a character easily effected by a coinpe'tent Workman, should be made in the timing; apparatus so that the circuit through the electro-magnet 9 is completed, and the 1inductive means be thereby rendered opcrative to produce an electric discharge in each operative position oi' the distributer. Having described my invention, l claiiii,
